I OOOOOOOOOOOOOOOOOOO ON Filed F INVENTOR. WILLIAM H. KING- ATTORNEYS.

Patented May 10, 1932 STATES WILLIAM H. KING, OF WEED, CALIFORNIA PANELnoon CONSTRUCTION Application filed February 24, 1931.

This invention relates to Wooden doors and has for its objects animproved construction whereby the panels or inner frames are more easilyaffixed in place, and whereby the use of nails is avoided in securingthe panel molds, also a construction which facilitates the manufactureof raised molding doors.

In the drawings accompanying this specification Fig. 1 is a verticalcross section of 1' a one panel door showing my improved construction.

Fig. 2 is a similar view of what is known as an inner frame door made inaccordance with my invention.

Fig. 3 is a similar view of a one panel door showing a modified form ofthe invention.

The common construction of wooden doors includes an outer frame which isgrooved around its inner edge to receive a panel, and the margins of thepanels are finished either by tacking strips of molding in place, or byrunning the molding directly on the inner edges of the frame.

In my improved construction I provide interlocking moldings which areapplied from opposite sides of the frame to interlock with one anotherin a glue joint and hold the panel between them, thus doing away withnails, or running the moldings on the frame.

In the figures 1 represents the door frame which may have one panelopening 2 or any number of them and which frame may further be a simplesolid section as shown or built up out of any number of pieces as iscommon in the better grades of doors.

The panels of the doors are designated 8, and in Fig. 1 these panels areshown held in place by means of moldings 1 and 5 applied from oppositesides of the frame and formed to overlap the frameat 6 and withinterlocking tongues and grooves 7 8, and also formed to provide agroove 9 to receive the .panel.

In this figure the tongue and groove are shown slightly beveled toproduce a tight fit 5 and in assembling the parts the molding joints andthe joint between the moldings (and frame are glued, though the groovefor the panel may be left free of glue if desired.

The ornamental part of the moldings may of course be of any desired formand the mold- Serial No. 517,775.

ings may project beyond the faces of the door are designated 4 and 5 andare the same as shown in Fig. 1 except that the tongue and grooves arenot shown tapered. In'this view the moldings do not directly hold thepanel 3, but hold an inner frame 10 which'in turn g holds the paneleither in a plain groove as shown or by further use of interlockingmoldings as at 4 and 5. In this view thewhole insert, i. e., the innerframe 10 plus the panel 3 may be considered as a panel insofar as themain or outer frame 1 of the door is concerned.

In Fig. 8 Ishow a modification of the invention in which the appliedmoldings 4", 5 are not made with integral tongues as in Figs. 1 and 2,but both are precisely alike and run with a simple groove 11 into whichis fitted a separate flat strip 12, the parts being glued and tightlyforced together when assembling as described for Fig. 1.

With either modification the frame of the door is made first and themoldings are mitered at the corners to fit the openings in the frame andforced together from opposite sides of the frame with glue in thejoints, after first laying the panels in place in the rabbet 13 formedin the inner corner of one member I of the molding.

While I show a clearance at 14 in the drawings and. with the moldingstight against the panels, this clearance may be omitted and the panelsleft slightly free if desired.

In my claims, the word panel is to be considered as also including theassembly of inner frame 10 of Fig. 2 when such construction is used.

I claim 2- 1. Apanel door comprising a main frame with an opening'forthe panel, moldings fitting within the o ening on opposite sides of nand overlapping tii embraced by the moldings and a lock joint on themoldings between the panel and the door frame.

e frame of the door, a panel ting Within the opening on opposite sidesof and overlapping the frame of the door, and a panel embraced betweenand by the moldings,

said moldings formed With interlocking tongues held together in a gluejoint.

3. A panel door comprising a main frame with an opening for the panel,moldings fitting within the opening on opposite sides of and overlappingthe frame of the door, a panel embraced between and by the moldings, andinteriorly interlocking means holding said moldings in clamping relationtoisaid frame.
